Mamp Local Server

Posted onby

MAMP is a free, local server environment that can be installed under macOS and Windows with just a few clicks. MAMP provides them with all the tools they need to run WordPress on their desktop PC for testing or development purposes, for example. With the help of our local DNS server NAMO, you can even easily test your projects on mobile devices. Sharing a Local Dev Server with Your Clients Using MAMP. Posted on May 25th, 2011 Workflow, Tips. For a while I’ve been trying to figure out the best way to share my local development environment with my clients. While this may not be the best way, it works for me and may work for you too. I have MAMP Pro 4 running on a Macbook Pro, with virtual hosts. It's working fine. I want to be able to access it from other devices on my local network in order to test various browser / os combinations. All the articles and posts I have found online are for earlier versions, and or don't seem to work, or require additional software.

  • This tutorial is a solution on how to solve the 'error to establish a database connection' when installing Wordpress locally in a MAMP environment.
  • I am currently developing a wordpress site locally using MAMP PRO, which obviously involves using a local database. I would like to test this site on my iPhone via a remote link. I have managed to do this by typing the following into my mobile phone URL.

My early experiences with web design and development only involved the front end - HTML, CSS and some JavaScript. As long as I had a browser, I was set. Eventually as a web developer, you get to a point where you need to implement PHP or some other back-end language. Maybe you need to install Wordpress or some other CMS, but you have no idea how to do that or what it entails. Whatever the case, it's impossible to be a serious developer without knowing how to work with a server.

The best way to get used to working on a server is to set up a local environment on your computer. If you know HTML, CSS, and JavaScript, but have never used PHP offline, this tutorial is for you.


  • Set up a local 'LAMP Stack' style environment - http://localhost:8888
  • Be able to run multiple servers, or 'virtual hosts' -

A Little About PHP

Any HTML file can be a PHP file. Take any .html file you have right now and save it as a .php file and try to open it. What happens?

I just did this with a basic HTML skeleton. If I had saved the file as index.html, all I would see is 'Hello, world!'. However, I saved it as index.php and this is what I got.

What Is Local Server looks like the browser is treating my PHP file as a text file. All it's doing is spitting the code right back at me. Well, that's completely useless. How do I get it to start interpreting the code?

That's where the LAMP stack comes in. LAMP stands for Linux, Apache, MySQL, PHP(/Python/Perl). It's an open source bundle of software applications that creates a dynamic web server environment. There is also MAMP and WAMP, for Mac and Windows, respectively.

To get PHP to start working, we don't need to understand how it works, anymore than you need to understand how an internal combustion engine works to drive a car. All I want at this point is my index.php to start interpreting code and markup.

There are two parts to this process: part one is getting your local environment set up in the first place; part two is setting up virtual hosts so you can access multiple local environments at once.

Part 1: Setting up a Local Environment

There are complicated ways to go about installing each component of the LAMP stack one by one - or you can download a program that does it for you. You can think of it as the difference between building your own computer from parts or buying one that's already put together. They both get you to the same end point, but perhaps you want extreme amounts of control or customizability. Well, we don't.

Whether you have a PC or a Mac, just download MAMP and install it on your computer.

Once the installation is complete and you open it, you end up at a screen like this.

Now click on Start Servers. If you're not in the administrator account, you might be prompted for the admin password. Once it's glowing green, everything is good to go. MAMP should open the WebStart page in a new tab in your browser. If not, you can click on Open WebStart page and it should take you to a page like this.

If you got a page like this, congratulations. You now have a local server and can run all the PHP you want. Go to Preferences > Web Server. Click on the folder next to document root and choose the directory you decided to place your PHP file in from earlier. Mine was sites/learnphp.

Now I'm going to go to http://localhost:8888 in my browser. What happens?

It's rendering the code! PHP is being parsed by all that stuff in the LAMP stack, and outputting regular HTML. But, we only had HTML to begin with. I want some sort of proof that this was all worth it. What's something simple that HTML can't do that PHP can?

Note for Windows users: the URL will simply be localhost, without the :8888.


The absolute beauty of PHP is that it can be inserted anywhere into HTML. Anything that goes inside the opening tag of <?php and the closing tag of ?> work it's magic on your server and return HTML.

I'm going to change my 'Hello, world!'.

The code <?php echo date('Y'); ?> uses a date function to find the year. The HTML interpreted is just '2015'.

That concludes the scope of this article - learning how to set up a local server environment and being able to run PHP.
